SASH LIFT.

Application filed August 6, 1926. Serial No. 127,581.

Ordinary, double-hung windows are provided with handles formed in the shape of a loop or bail which are screwed to the inner face of the lift rail. According to the g present invention, I have found that sash lifts can be made of a very neat a pearance and inexpensively if the lift rail 1s formed with an inwardly extending projection and a member is shaped to fit over this projection with ridges to give a good grip for the fingers. This provides a very solid lift member and the pressure will be exerted more directly in the plane of the sash than Where the handle is in the form of a loop. 1 This will tend to make the sash operate more easily; also there is no danger of catching the fingers in the handle and twisting them as the angle changes if the sash runs up rapidly.

An illustrative example of my invention is shown in the accompanying drawings, in which Fig. 1 is a section on line 1-1 of Fig. 2 and Fig. 2 is a face view of the lift taken from the inside.

The numeral 10 represents the bottom member of the sash proper to which is attached in any convenient way (as by screws not shown) a glass stop 12. In the example illustrated, the sill 14 is provided with a valley 16 and an upwardly extending projec- 1m tion 18 which is embraced between the mem ber 10 and the glass stop 12.

The upper edge of the glass stop .12 is bent inwardly to form a ridge 20, the sides of which are substantially parallel. The :1; lift handle is provided with two legs 24 and 26 shaped to fit around the projection 20 and has two flanges 28 and 30. I prefer to make the handle thussymmetrical, as it adds to its appearance and makes less trouble in in putting it in place. Also the upper flange 28 serves to give a good grip for pnlh ing down the sash, while the flange 30 serves for lifting. The handle 22 is here shown as attached to the member 12 by screws 32, at but it is obvious that it may be attached in other-wa s as by riveting.

What i claim is:

In combination, a sash having an inwardly extending projection formed on the lift so rail, and a substantially symmetrical lift handle embracing said projection and attached to it, provided with flanges adapted to be engaged while raising and lowering the sash. i
